Embeddable Build Status Icon

Jenkins exposes the status of the specific build as an image in a fixed URL. You can put this URL into other sites (such as GitHub README) so that people can see the state of the specific build. There are two URLs available for inclusion:

protected exposes the badge to users having at least Read permission on the job

unprotected exposes the badge to users having at least ViewStatus permission on the job

If you want the status icons to be public readable/accessible, just grant the ViewStatus permission globally to anonymous.
